These tools were designed for z/OS UNIX by IBM developers and testers. Unless otherwise noted, most of the tools are not very portable. They probably will not work well on other UNIX systems without at least a little modification. The packages provided here are working to the satisfaction of the people who ported them. If you have a problem working with a package, open an issue.
